14.5 is what percent of 129.5 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 129.5 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 129.5, so we can write it down as 100%=129.5.
4. We know, that x% equals 14.5 of the output value, so we can write it down as x%=14.5.
5. Now we have two simple equations:
1) 100%=129.5
2) x%=14.5
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=129.5/14.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 14.5 is what percent of 129.5

100%/x%=129.5/14.5
(100/x)*x=(129.5/14.5)*x       - we multiply both sides of the equation by x
100=8.9310344827586*x       - we divide both sides of the equation by (8.9310344827586) to get x
100/8.9310344827586=x
11.196911196911=x
x=11.196911196911

now we have:
14.5 is 11.196911196911% of 129.5
